Okay, I've searched for the answer to this and haven't been able to find it, but I know that it's on WhiteBlaze somewhere.
I understand that you can't dehydrate a frozen dinner (e.g. Lean Cuisine, Smart One, Michaelina, etc.) because the company says to not thaw their product prior to cooking because of risk of bacterial contamination.
But, if you were to cook a frozen dinner first according to the directions on the box, could you then safely dehydrate the cooked meal and then just rehydrate with boiling water on the trail? In my mind, this would be no different from cooking spaghetti at home and then dehydrating the left-overs, as so many people do.
It just seems too easy to do this, but no one is mentioning this anywhere, so I assume there's a problem with this idea? Anyone got any advice on this?
